    IntroductionA surge in critically ill patients with respiratory failure due to Covid-19 has overwhelmed ICU capacity in many healthcare systems across the world. Given a guarded prognosis and significant resource limitations, less invasive, inventive approaches such as prone positioning (PP) of non-intubated patients with hypoxemic respiratory failure were considered.Aims And ObjectivesThis is a prospective observational study and the aim is to evaluate the impact of awake PP at the ward level on the oxygenation levels of patients with COVID-19. We also are investigating as secondary outcomes, the risk factors for treatment failure among awake non-intubated patients who tolerated PP compared to those who did not. The primary outcome of this trial is the change in SpO2:FiO2 (SF) ratio from admission to discharge in the participants who tolerated PP compared to those that did not. Secondary outcomes included amongst others are ICU admission rate, in-hospital mortality, and length of stay.MethodsA total of 63 patients admitted to Beaumont Hospital (BH), Dublin between January and February of 2021 with Covid-19 requiring supplemental oxygen were recruited.ResultsA total of 47 (74%) participants were reported as tolerating and 16 (26%) as non-tolerating PP. The mean rank in the primary endpoint in the tolerating group was 38 vs. 16 in the non-tolerating. This was statistically significant (P < 0.001).ConclusionPP was associated with improvements in oxygenation parameters without any reported serious adverse events. A well-designed, randomised control trial, testing the efficacy of PP in non-intubated Covid-19 patients is needed, before the widespread adoption of this practice.© 2022.
